Hello all,

I have been confusing the output characteristics of NPN and PNP. Please can any one draw the graphs and explain?.

 

Show us what circuit you are talking about. There are many configurations that can be used with different output characteristics.

I am talking about general output characteristics.

 

There is not such thing. You need a circuit before you can talk about output.

I am talking about general output characteristics.

Each output requires an input. There are - in principle - three different input-output characteristics. Which are you interested in?

 

Transistors have three basic configurations and they each perform different functions. The configurations are:

1. Common Emitter
2. Common Base
3. Common Collector

Pick one and we can continue the conversation.

 

Or perhaps you should just explain what you mean by "output characteristics". That might help.

The fundamental difference between an NPN and a PNP bipolar transistor is that, when in the active region, the collector and base of the NPN are more positive than the emitter, and for a PNP the collector and base are more negative than the emitter.
So identical circuits can be built with either, but the signal and bias polarities will be opposite.

Post #9 completely answers your first question. Do you have other questions?
